Microchip Technology's AT28HC64B-70JU-T is a 64-kilobit (8K x 8) CMOS Parallel EEPROM. This device offers a fast 70ns access time, enabling efficient data retrieval in demanding applications. Designed for robust operation, it features a data retention of at least 10 years and an endurance rating of 100,000 write cycles. The AT28HC64B-70JU-T supports a standard 5V programming voltage and operates asynchronously. Its 32-pin J-lead PQCC package (R-PQCC-J32) is suitable for surface-mount assembly. This component finds application in industrial control, automotive systems, and telecommunications infrastructure where reliable non-volatile data storage is critical. It includes data polling and toggle bit features for enhanced write operation management.
